Immediate loading of the maxilla with prefabricated interim prosthesis using interactive planning software, and CAD/CAM rehabilitation with definitive zirconia prosthesis: 2-year clinical follow-up

Immediate loading in implant dentistry has provided several advantages for both patients and clinicians. Recent advances in computer-aided design/computer-aided manufacturing (CAD/CAM) technology, medical imaging and rapid prototyping have added to the armamentarium of implant dentistry in terms of efficiency, accuracy and predictability. Rapid prototyping and CAD/CAM technology are used to fabricate stereolithographic surgical templates for flapless implant placement. In addition to that, this technology is also used for the fabrication of zirconia frameworks. The zirconia-based implant restorations are gaining popularity in implant prosthodontics combining esthetic properties with strength and biocompatibility. The purpose of this article is to illustrate the steps for implant rehabilitation of the edentulous maxilla with zirconia prosthesis and report the 2-year clinical follow-up of novel technological advances in surgical placement, provisionalization and fabrication of a definitive restoration.
